read_streaming io state is an image frame, its suggested display time (in hundredths of a second; for animations), and optionally the state required to read the next frame.

The first invocation should pass state = None to initialize a new reading context.

If the resulting read_state option is None, there are no more image frames available in io. If it is Some st, st must be passed to the next invocation of read_streaming.
